A human-sized hamster wheel in which visitors can generate electricity is among the three new exhibits at a science centre.

The new additions at Xplore! Science Discovery Centre, on Henblas Street in Wrexham, are part of an investment worth £120,000 and will join the centre's existing 80 displays.

The human-sized hamster wheel, which generates electricity through movement, is designed to encourage visitors to be more environmentally conscious by demonstrating the power requirements of everyday objects.

The second of the new exhibits is a stop-motion animation table, which enables guests to adopt the role of a filmmaker by developing their own stories using objects and figurines.

The new additions were decided upon following a series of consultations with specialists Science Projects and Whitefire, and were funded by the UK Shared Prosperity Fund.

Xplore!’s education officer, Jennifer Hough, said: "We are always looking for ways to engage with our visitors, and I believe our most recent additions bring scientific concepts to life like never before.

"Not only are the new installations the first of their kind for us here at Xplore! but they are currently the only exhibits of their kind in North Wales.

"They truly highlight the varied world of STEM and appeal to all audiences.

"We want to cater to both regular and first-time guests so adopting a mixture of familiar and never-seen-before exhibits will help us achieve that.

"Overall, we hope the changes will inspire all our visitors to see the fun and innovative side of STEM."
